Transhiatal esophagectomy using a ring dissector.
Subtotal esophagectomy may be performed without thoracotomy by transhiatal dissection. We describe an alternative to the classical technique of transhiatal manual blunt dissection of the esophagus using a ring dissector, which allows a less traumatic dissection of the esophagus above the carcinoma of the esophagus. This instrument, designed for this particular purpose, produces a rapid and clean blunt dissection.
